SUMMARY:An ionised bubble before the epoch of re-ionisation
DESCRIPTION:An ionised bubble before the epoch of re-ionisation\nDr. José 
 Miguel Rodriguez Espinosa\n\nRe-ionisation followed the dark ages when eno
 ugh stars and galaxies had been formed that their ionising output was suff
 icient for the task. Population III stars and star-forming galaxies starte
 d the re-ionisation process by forming primordial bubbles of ionised gas. 
 These bubbles grew, illuminated by galaxies with strong Lyman continuum, a
 nd merged, till the entire Universe became ionised. The epoch correspondin
 g to red-shift 6.5 is especially interesting as we now know the Universe b
 ecame re-ionised by redshift ~5.5-6. High-z Lyα emitters are perhaps
  the most important witnesses of the re-ionisation process. Indeed, at red
 shifts larger than 6, Lyα sources would be undetectable, unless they
  are located within sizeable bubbles of ionised gas. I will show that a pr
 oto-cluster of Lyα emitting galaxies, spectroscopically confirmed at
  redshift 6.5, is within one such large ionised super-bubble. The kinds of
  bubbles that through percolation completed the re-ionisation of the unive
 rse.\n \nZoom link  https://rediris.zoom.us/j/94401326592
